A digital forensic investigation is a specific type of digital inquiry where methodologies and techniques are employed to enable results that can be presented in legal frameworks. This investigation might begin to ascertain if counterfeit digital images are present on a computer. For instance, Global Finance Company, which has a broad range of financial products and clients globally, finds itself in a situation where a breach has been reported involving the manager's computer. In response, a team is dispatched to the branch for the digital forensic investigation. Concerns highlighted by the company include: 1. Timely updates of application and network infrastructure. 2. A report from a branch manager in Brisbane expressing concerns of possible breaches. 3. All office servers and workstations primarily utilize Microsoft Windows. 4. Full implementation of firewalls and network segregation. 5. Although there is intrusion detection and logging across branches, their application has been neglected. The digital forensic investigation follows a structured approach comprising four phases: Collection, Examination, Analysis, and Reporting. The investigation model used proves to be effective for assessing the security incident at the regional branch. 1. In the Collection phase, data from the manager's workstation and all relevant servers must be gathered systematically. This includes identifying both internal and external storage contexts and ensuring availability of necessary forensic tools. The imaging of target computers is also crucial, along with hashing to maintain data integrity, while capturing network traffic. 2. The Examination phase involves a comprehensive analysis, comparing original data against logical copies to derive insights concerning system registry evaluations and other critical data points. Tools used for this include specific commands to assess file retrieval. 3. In the Analysis phase, various methodologies are employed, including keyword searches, file recovery, and registry data extraction, utilizing tools like FTK and ILOOKIX to access essential documents. 4. Finally, the Reporting phase concludes the investigation with the audit team generating a comprehensive report detailing the incident's summary, analyzing data, and concluding findings, while also supporting documentation with both volatile and non-volatile evidence.

Answer:

Step 1: Create a table reflecting the three potential scenarios and two possible outcomes. There should be a total of 8 distinct rules for the three varying conditions, structured similarly to the discount table shown here in the example: attached is the discount table

Step 2: The rules can now be made simpler by taking the following aspects into account:

a) When a consumer completes the survey form AND opts into the newsletter, according to Rules 1 and 2, they qualify for a discount if their order exceeds $100. This leads to two distinct rules being formulated while the third condition (order quantity) holds significance.

b) If the buyer fills out the survey form OR subscribes to the newsletter, as indicated by Laws 3, 4, 5, and 6, they will benefit from free shipping, regardless of the order amount. As a result, this situation can be divided into two individual rules, where at least one requirement is satisfied, but not both.

c) When a customer fails to meet any requirements, corresponding to Rules 7 and 8, the order value will not qualify for either free shipping or discount. This can be seen as a single law. The linked simplification table illustrates this.

Answer: Scanners used in supermarkets for barcodes and voice-activated phone menus are not examples of artificial intelligence.

Explanation:

(a) Supermarket barcode scanners can read codes, yet they lack the capability to employ machine learning techniques for learning patterns within the codes. Machine learning is a crucial aspect of artificial intelligence (AI), thus indicating they do not qualify as instances of AI. Likewise, voice-activated menus can only present options and do not carry out any complex tasks.

In contrast, web search engines and internet routing algorithms demonstrate dynamic and intelligent capabilities in processing and delivering information to users.

Hence, these are considered examples of AI.

Answer:

Below is the Python code with suitable comments.

Explanation:

#Input file name acquisition

filename=input('Enter the input file name: ')

#Opening the input file

inputFile = open(filename,"r+")

#Dictionary definition.

list={}

#Read and split file content using a loop

for word in inputFile.read().split():

#Check if the word exists in the file.

if word not in list:

list[word] = 1

#Increment count by 1

else:

list[word] += 1

#Closing the file.

inputFile.close();

#Output a blank line

print();

#Sorting words according to their ASCII values.

for i in sorted(list):

#Display unique words along with their

#frequencies in alphabetical order.

print("{0} {1} ".format(i, list[i]));

Answer:

C3H8

Explanation:

Step 1:

Relevant details from the question are noted below:

Mass of the alkane is 1.17g

Volume (V) = 674 mL

Temperature (T) = 28°C

Pressure (P) = 741 mmHg.

Gas constant (R) = 0.08206 atm.L/Kmol

Step 2:

Convert to the appropriate units.

For Volume:

1000mL = 1L

So, 674mL = 674/1000 = 0.674L

For Temperature:

Temperature in Kelvin = Temperature in Celsius + 273

Temperature in Celsius = 28°C

Temperature in Kelvin = 28°C + 273 = 301K

For Pressure:

760mmHg = 1atm

So, 741 mmHg = 741/760 = 0.975atm

Step 3:

Calculate the moles of the alkane.

The moles of the alkane can be found using the ideal gas equation, presented below:

Volume (V) = 0.674L

Temperature (T) = 301K

Pressure (P) = 0.975atm

Gas constant (R) = 0.08206 atm.L/Kmol

Number of moles (n) =?

PV = nRT

n = PV /RT

n = (0.975 x 0.674)/(0.08206x301)

n = 0.0266 moles

Step 4:

Calculate the alkane’s molar mass.

Mass of alkane = 1.17g

Number of moles = 0.0266moles

Molar Mass =?

Number of moles = Mass/Molar Mass

Molar Mass = Mass/Number of moles

Molar Mass of alkane = 1.17/0.0266 = 44g/mol

Step 5:

Determine the molecular formula of the alkane.

This is based on:

The general formula for alkanes is CnH2n+2

To find the molecular formula, we start with n = 1, 2, 3, etc., until we find the molar mass of 44.

When n = 1

CnH2n+2 = CH4 = 12 + (4x1) = 16g/mol

When n = 2

CnH2n+2 = C2H6 = (12x2) + (6x1) = 30g/mol

When n = 3

CnH2n+2 = C3H8 = (12x3) + (8x1) = 44g/mol

It can be observed that for n equal to 3, the molar mass is 44g/mol.

Thus, the molecular formula of the alkane is C3H8.
